Figure 15 is a detail perspective View of a modified form of crank armbearing.

In practicing my invention, as illustrated in Figures 1 to 9 inclusiveof the drawings, I provide a frame 5 equipped with upper and lowerdetachable frame sections 6 and I respectively. The upper frame section3 comprisesa pair of spaced side walls 8 having their lower endsintegrally connected together by a transverse lower wall 9 and theirupper ends fashioned to define a handle It One of the side walls 8 isfashioned, between its upper and lower ends, with a pair of spaced armsI l extending towards the other side wall'and constituting bearings I Ithrough which are journaled upper and lower ends of a verticallydisposed shaft I2.

The upper and lower ends of the shaft I2, above and below said bearingsI I, have mounted thereon frustum-shaped elements I3 and Hillrespectively frictionally engaging a similar shaped element I4interposed therebetween and coacting therewith to constitute africtional drive means for said elements I 3 and Ita. The element I4 isfixed to the inner end of a crank arm I5 provided with a handle 5 5a andwhich is journaled in a bearing it carried by one oithe side walls 8.

Sleeved about the hearing it, between the element it and the adjacentside wall 8, is a coil spring Ii' urging said element I4int0 engagementwith the elements it and I3a whereby operation of the crank shaft Itserves to impart rotation to said'elements I3 and I361. The upperelement i3 is keyed to the shaft I2 for effecting rotation of the latterwhile the lower element [31; is rotatable with respect to said shaft I2and is formed with an elongated hub I8 having a lower end journaled forrotation in an aperture formed in the wall 9 and is provided adjacentsaid. lower end with a flange I9 overlying said wall 9 as clearlyillustrated in Figure 3 of the drawings.

- The outer ends of the wall 9, adjacent the lower ends of the walls 8,are formed with slots 9a through which slidably extend the upper ends ofbowed-shaped arms 29 comprising the lower frame section I, the lowerends of said arms 20 being integrally connected together by a transverseportion 2i. The upper ends of the arms 20 terminate in right angularlydisposed fingers 22 detachably seated in recesses 23 formed in the upperface of a transversely disposed plate 24, the latter being provided witha centrally disposed opening 25 through which extends the hub ii] of thelowermost element I3a. Subjacent their upper ends; the arms 2d areformed with outwardly disposed abutments 290:. which engage the underface of the wall 9 adjacent the slots 9a and thereby limit the upwardmovement of the lower section l with respect to the upper section 6.

Adjacent their lower ends the side members 8 are provided with inwardlydisposed guides 26 embracing the sides of the upper ends of the arms 28whereby to preclude relative lateral movement therebetween. Sleevedabout the hub I8 is a coil spring 21, the lower end of which engages theflange I9 while the upper end engages the under face of the plate 24whereby said spring normally maintains the fingers 22 seated in therecesses 23 of the plate 24.

The lower ends of the shaft [2 and hub 18 extend an appreciable distancebelow the wall 9 and have fixed thereto drive members 28 and 28arespectively and with the drive member 28a arranged between the drivemember 28 and the wall 9. The drive members 28 and 28a are fashionedwith square-shaped tenons 29 and 30 respectively as clearly illustratedin Figure 9 of the drawings. Obviously, upon rotation of the element Itthe drive members 28 and 28a will be rotated in opposite directions.

The tenons 29 and 30 seat within square-shaped apertures 31 and 32respectively formed in the upper transverse bars of inner and outeragitators 33 for effecting rotation of the agitators by the members 23and 28a, the lower ends of the agitators being pivotally and detachablyconnected to a trunnion 34 carried on the portion 2| as clearlyillustrated in Figures 1 and 2 of the drawmgs.

, Obviously, by operating the crank arm [5, rotary movement is impartedto the agitators 33 in the usual manner for beating or whipping foodstuffs and the like. By pressing the plate 2% downwardly and rotatingthe same with respect to the fingers 22, the arms 20 may be moveddownwardly with respect to the upper frame section 5, it beingunderstood that the slots 9a are of a suificient length to permit thefingers 22 to pass therethrough thus enabling the lower section to bedetached from the upper section. Reverse 0per'ation serves to repositionthe parts in the manner disclosed in Figures 1 and 3 of the drawings.When the lower section is thus detached from the upper section, theagitators 33 may be readily removed from the lower frame section 1 forcleaning. Furthermore, if desired, the lower frame may be lowered only asumcient distance to permit the agitators 33 to be disengaged from themembers 28 and 28a.

As illustrated in Figures 10 to 14 inclusive of the drawings, I providea frame 5|] equipped with upper and lower detachable frame sections 5|and 52 respectively. The upper frame section 5! comprises a pair ofspaced side walls 53 having their lower ends integrally connectedtogether by a transverse lower wall 5d and their upper ends fashioned todefine a handle 55. One of the side walls 53 isfashioned, between itsupper and lower ends, with a pair of spaced arms 56 extending towardsthe other side wall and constituting bearings 51 through which arejournaled upper andlower ends of a vertically disposed shaft 58.

The upper and lower ends of the shaft 58, above and below said bearings,have mounted thereon upper and lower pinions 59 and 59a respectivelymeshing with a gear 6!] interposed therebetween and coacting therewithfor driving said pinions 59 and 59a. The gear 50 is fixed to the innerend of a crank arm 6| provided with a handle 62 and which is journaledin a bearing 63 carried by one of the side walls 53.

The upper pinion 59 is fixed to the shaft 53 while the lower pinion 59ais loosely mounted on said shaft 58 for relative rotation therewith andis fashioned with an elongated hub 64 having a lower end journaled forrotation in an aperture formed in the wall 54 and is provided, adjacentsaid lower end, with a fiange 65 overlying said wall 54 as clearlyillustrated in Figure 12 of the drawings The outer ends of the wall 54,ad'- jacent the lowerends of the walls 53, are formed with slots 56through which slidably extend the upper ends of bowed-shaped arms 61comprising the lower frame section 52, the lower ends of said arms 61being integrally connected together by a transverse portion 68.

The upper ends of the arms 61 terminate in hook-shaped fingers 69 towhich are connected the lower ends of coil springs 70. The upper ends ofthe springs are connected to hooks ll formed on the side walls 53.Subjacent their upper ends, the arms 5'! are formed with outwardlydisposed abutments 72 which engage the under face of the wall 55adjacent the slots 66 and thereby limit the upward movement of the lowersection 52 with respect to the upper section 53. The coil springs H1serve to normally maintain the abutments E2 in engagement with the wall54, thus effecting connected relation between the frame sections 5| and52.

Adjacent their lower ends the side members 53 are provided with inwardlydisposed guides 13 embracing the sides of the upper ends of the arms tiwhereby to preclude relative lateral movement therebetween. The lowerends of the shaft 58 and the hub 64 extend an appreciable distance belowthe wall 5-4 and have fixed thereto drive members l4 and Ma arrangedbetween the member lid and the wall 54. The members 74 and 1411 areadapted for rotation in opposite directions with respect to each otherand are fashioned with square-shaped tenons l5 and 75 respectively.

The tenons l5 and 56 seat within square-shaped apertures formed in theupper transverse bars of inner and outer agitators l! for effectingrotation of the agitators, the lower ends of the agitators beingpivotally and detachably connected to a trunnion 73 carried on theportion 68 as clearly illustrated in Figures 10 and 11 of the drawings.

Obviously, by operating the crank arm 6|, rotary movement is imparted tothe agitators T1 in the usual manner for beating or whipping food stufisand the like. By pressing the lower section downwardly, the arms 61 aremoved downwardly with respect to the upper frame section 5!, it beingunderstood that the slots 55 are of a sufiicient length to permit thefingers 22 to pass therethrough, upon removal of the springs Ill, thusenabling the lower section to be detached from the upper section.Reverse operation serves to reposition the parts in the manner disclosedin Figurs l0 and 11 of the drawings. When the lower section is thusdetached from the upper section, the agitators Tl may be readily removedfrom the lower frame section for cleaning. Furthermore, if desired, thelower frame may be lowered only a sufiicient distance to permit theagitators H to be disengaged from the members 14 and Ida to permitremoval for cleaning.

As illustrated in Figure 15, one of the side walls $0 of the upper frameis provided with a crank arm bearing 8! extending therethrough and toreenforce said bearing the wall has a portion 82 struck therefrom withthe latter formed with a depending section 33 receiving the outer endsection of the bearing 8|, thereby minimizing whipping action of thecrank arm.

WVithout further elaboration, the foregoing will so fully explain theinvention that others may, by applying current knowledge, readily adaptthe same for'use under various conditions of service. Moreover, it isnot indispensable that all the features of the invention be usedconjointly since they may be employed advantageously in varioucombinations and sub-combinations. l

t is obvious that the invention is not confined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable. It is therefore to be understood that the invention is notlimited to the specific construction as illustrated and described, asthe same is only illustrative of the principles of operation, which arecapable of extended application in advance forms, I
